Given the importance of language, cognitive flexibility and behavioral IC skills to children’s academic success and socioemotional functioning, longitudinal investigation into their foundational biological and behavioral precursors is an important task for developmental science. Further, because deficits in these different domains of cognition frequently co-occur (Alarcón-Rubio, Sánchez-Medina, & Prieto-García, 2014), and the relations between these constructs are not well understood, it may be especially informative to study them conjointly. The purpose of the current study is to examine the longitudinal associations between changes in frontal EEG coherence across the second half of the first year, attentional control in late infancy, and higher cognition in early childhood.
